Abstract

1,200,919. Mixing apparatus. BAKER PERKINS Inc. 21 Dec., 1967 [12 Jan., 1967], No. 58197/67. Heading B1C. [Also in Division B3] A continuous kneading and mixing apparatus has two shafts 16, 17 rotating in the same direction and at the same speed and carrying paddles 18, 19 each arranged to wipe the cooperating paddle on the other shaft; as shown they are lenticular. Axially successive paddles are offset by 90 degrees and they are connected by transition sections 20, 21 each consisting of four symmetrical curved surfaces 20a, 21a. Such a shaft with paddles and transition surfaces having maximum heat exchange characteristics may be made by deforming a tube (see Figs. 3-5A, not shown). In another embodiment the-shaft and paddles are solid; each paddle has appreciable axial length and is formed by four lenticular paddles (18', 19') which are offset to form a helix, and have themselves a helical pitch and arcuate crests (34), see Figs. 6-8 (not shown). In a modification (Fig. 9, not shown) the paddle sections have no pitch and do not form a helix.
